[1]
Curated associations are established by CTD (chemical–disease and gene–disease) and OMIM (gene–disease) curation.
[2]
Inferred associations are established via CTD-curated chemical–gene interactions (e.g., Chemical A is associated by inference with Disease B because Chemical A has a curated interaction with Gene C, and Gene C has a curated association with Disease B).
